Chapter , Problem 15(choose chapter or problem)
The two vectors \(\vec{a}\) and \(\vec{b}\) in Fig. 3-28 have equal magnitudes of 10.0 m and the angles are \(\theta_{1}=30^{\circ}\) and \(\theta_{2}=105^{\circ}\). Find the
(a) x and
(b) y components of their vector sum \(\vec{r}\),
(c) the magnitude of \(\vec{r}\) , and
(d) the angle \(\vec{r}\) makes with the positive direction of the x axis.
